Improvement in grain-doors for cars



,LAURENCE EFRAZEE, CF JERSEY CITY, NEW JERSEY.

Letters Patent No. 114,661, dated May 9, 1871.

' IMPRQVEMENT IN GRAIN-DOORS FOR CARS.

The Schedule referred to m these Letten Patent andmaklng part of the sme.

lTo all whom it may concern y Be it known that I, LAURENCE F. FRAZEE, of Jersey City, in the county ofnHudson and/:State of New Jersey, have invented a cerf-ain new and useful Improvement in Grain-Cars; -and I do hereby declare the following to be `such a full, clear, and exact desoriptionof-thesaaneas will enable any eue-skilled in the arts to which my invention appertains to make and use the saine,- reference being had to the accom.- panying drawingimaking partof this specification, in which- K v Figure 1 is a longitudinal vertical section through "a car with my improvement applied'thereto, and

Figures 2 and 3 are transverse vertical sections through said car, showing two dilierent aspects of the improvement aioresaid.

'My invention consists in. a novel construction and application of the door of the car, by which said door, when the oar comes to be unloaded, is gradually relieved ofthe pressure against it, and can be readily raised and removed out of the waytlie workmen engaged in .discharging the car.

Iu' the drawing- A represents the body of the car. Y

B represents the outside door thereof', arranged to slide horizontally outside of the car.

Inside oftbis door the grain-door C is arranged. It is rectangular in forni, and consists of planks duly' joined together, and is arranged to slide up and down in grooves made in the side-door postln the vmanner shown. Each end of this door is hung upoua pivothinge,consisting of the socket-pivot J and the socket Y V l, which last is raised upon the plate F bolted to the outside of the door' aforesaid.

The socket end of each pivot J is made' to slide .up and down uponA a long staple xed to the inside of each side-door post, so that the door, when raised up or let down, is held in position by these straps and pivot-hinges.

Now, this door, when. the car is iilled with grain, is pressed so hard against its bearing that it is mpossi blel to raise it without injury to the body or door. To avoid this I make a slide-gate, D, in the door, and t it witha connecting-rod, 0, to which I attach a block and fall or screw, by which Iean readily open it and let out enough of the grain to relieve the grain-door proper sufficiently to allow it to be raised with ease, and so allow the grain to be discharged without iui jury to the door or cars. y

After the grain-door has been thus raised, as above described, itis swung over in a horizontal position, as shown in iig. 2, and is then raised up audfasteued under the roof of thecar by means of the staples f f.

Having now described the natureand extent of my invention,

I claim as new herein and desire to secure by Letters Patent- The kdoor O, fitted with a gate, D, and arranged ou pivot-hinges and sliding rods, as described, wheu combined with the body of a car suitable `for the transportation of grain or other similar substance iu bulk.
